Trogdor65, what do you mean by a "jam" is the dart not coming out but the gun is firing?
Or is the dart not loading?

If is it because the dart is not coming out but the gun is firing, it could be because you took out the nub that keeps the dart in the firing position and it slid forward enough so that it will not fire (can't tip the gun downwards when cocking) I have a problem of the dart sliding out when I tip my gun down and I am working on a fix for this (more to come later).

I don't know if anyone has done this yet, but I put a stretched out Maxshot spring in my LS. It is literally the same diameter as the LS stock spring, but a thicker gauge steel and much better performance. I haven't measured distances, but I can see that it out shoots the stock spring. Just throwing in my 2 cents. Good job Carrtoon.

I can't get the orange cocking peice off the metal rod to mod the gun. I read in another thread someone said to pry it with a screw driver. I tried yesterday and it won't come off. I was prying so hard I was afraid I would break the shell. Any other ideas of how to get it off? :D


I used a hammer to get it open. Just took the side you pry nails out with and pulled the piece off. It was much easier then the other method people have been using.

I use 2 BB's in my CDT's, maybe that's the problem. I've also heard of people using 3, so your darts are probably too light. Try making some with 2 or 3 BB's.

I find that 1/4" Slingshot weights are the best weights out there. Try those, and they will fly much further than stock darts.

I took out all restrictors, plugged all holes and am using CDTS with 3 BBs. Why am I only getting less than 40 ft. I also added a BBB spring, added.

Cole, I'd add a other o-ring or two. It is easily one of the most cost effective mods that can be done to are springer.

Also, does anyone happen to know how 19/32" brass compares to cpvc as far as OD. I put a piece of cvpc down the barrel to try to firgure out what size brass I'll need, and it fit all most perfect. It think Viper's PETG would be perfect for a barrel replacement.

I used rubber bands to keep the o-ring in place. CPVC is too huge for the guiding rail to slide over it, I tried. It is also really hard to even manually load the dart in. And anyway, with the CPVC jammed all of the way back and a dart in the end the dart wont even fire, at all.

I know that. If you read my post correctly, you would have seen that I was wondering how the outer diameter of CPVC compares to the OD of 19/32" brass, because I found that the OD of CPVC was almost perfect. But sorry if I didn't make it clear enough in the first post.

Oh, sorry. I would still very much like to get some input on how to make my LS suck less.

Sam, the OD of CPVC is .627 inch. The outer diameter of 19/32" Brass (assuming you mean K&S brass tubing) is in fact 19/32" or .593 inch. The OD of 9/16" brass tube is .562, thus also being the inner diameter of 19/32" brass. And FYI the ID of CPVC is .469 - yes, this is the American NSF-U.P.C. CPVC pipe.
I hope I've helped you.
I love my new calipers. :rolleyes:

Just finished my first round of modification. Many many thank to Carrtoon for the details. Made it fairly easy for me to knock out the basics in one night. I removed the restrictor, plugged the over-pressure hole using a set screw, added a second o-ring, and replaced the stock spring with a trimmed AR-15 spring.
Posted Image
The replaced spring is much stiffer and gives a more satisfying sound and priming action. I now get a much more noticable "puff" from the barrel when dry-firing.
After that I did an ergonomic upgrade. Sanded that annoying corner off of the butt stock and padded it down with some craft foam held on permanently with liquid nails. Made the gun much cozier with the stock collapsed.
Posted Image
And just a little foam on the left side of the grip.

For the benefit of others I took some high-res internal photos of the stock weapon for reference. The sequence shows the priming cycle.

I'm happy so far. No idea on ranges because I didn't finish until 1am. Preliminary tests in the basement were really impressive because I was shooting a wall 30 feet away and the darts were bouncing off the wall and making it most of the way back to me.

Things I still want to do
+ barrel replacement.
+ Make a foregrip extension to replace the stock priming handles.
+ Make a higher capacity clip.
+ Paint!

I'd love to see a custom paint job for the LS, I have yet to find one. If you do replace the barrel with, say, brass would you, say....mind doing a writeup for those who, say...might want to brass mod theirs? No one in particular...I just thought some people might want to see. Thank you.



On behalf of those people.

Sure, I could do a more detailed write-up. Carrtoon showed a little bit of how it can be done in post # 90

First you add a slight lip on the inside of the bolt after removing the restrictor peg. The dart gets "swallowed" by the bolt thanks to the stop-gate peg in the barrel.
Next you work on the barrel because it's placement is dependent on the location of the lip you added to the bolt.
The stock barrel has a needlessly high inner diameter so it's extremely easy to nest a brass or polyester barrel inside. Nesting a cpvc barrel would require some lathe work.
9/16" Brass is very thin walled and may have to be padded or nested in 19/32" in order for it to be held securely in the barrel collar.

Also something I noted while dissecting the gun that loks quite promising is that the plunger and trigger catch plates are both fairly simple dimensionally and should prove to be fairly easy to replace. The only part I see that could prove to be a concern is the removable rear plate on the plunger chamber. It's held in place only two very small screws

Wow, thanks! I'll use this and Carrtoon's post as guides. I was wondering, would it be better to put some wider brass in the rear part of the breech so it can slide over? Or did I just miss that part?

You'll want the two diameters to be the same to get the best seal. But whatever you choose there still has to be room for the tooth on the bolt to fit over the top of the new barrel insert.

It makes more sense when you have the gun entirely dissected by you may be able to get the idea from the pictures I posted of the insides.

Alright. Those pics are great, by the way. So I guess you don't want a higher diameter rear breech piece to overlap the smaller one? I thought that would form the best seal, but I see what you mean now.

That thing is beast! Nice!

Did it take a lot of dremeling to fit the LS side arm in that area?

That is coolest LS mod yet.

Ah I see. You can try doing so using 9/16" and 19/32" brass.

Neither insert can extend out of the stock piece without getting in the way of the magazine so you'll have to get the spacings right.
I did have some clearance issues with the bolt face and the magazine lip when I replaced the spring in my gun and the easiest solution was to simply sand down the lip on the magazine a little bit.

Cool. I just so happened to get some lengths of 19/32" to add to my brass collection. The fit is so tight I'm a little worried that if I don't do it jussst right, then it may not fit. I guess perfection is needed. Thanksamillion for the help! :P

Great, and for Carttoon, could I get some of that barrelling that you used? If not could I buy PTEG from someone at the right length for a LS barrell?

Carrtoon used the case from a drill bit, so you'd be better off using some brass or PETG.

I might repaint the sight grey instead of white. The front section was trimmed a bit in preparation for the fore-grip priming handle I will be machining tomorrow.

Well here is my mod of the longshot, same thing as other people, but instead of a longshot spring I used the Home Depot spring (same one as the one used for NF spring replacement mods). I cut about 4 loops off of the spring and still it is very hard to cock with one hand (Feel the muscle burn, and no I am not weak).

The other thing that I did different is the barrel, I used the barrel from the the front gun (I removed it as per the Longshot Front Gun Mod) I haven't tested it for ranges (still working on the dart mods) but it works quite well indoors.

Posted Image


I am wondering did you cut the barrel? because I am thinking about doing this, but it looks a little short?.
Thanks!
